I'm off on hols next week and need a bag for lugging my / toddler stuff on ferry, that will double as a beach bag to fit towels and swim stuff / snacks / further toddler stuff. So a non leather, massive tote, ideally with a zip. Have been in every shop in town with no luck - is Le Pliage worth the ££ and what size should I go for? I can almost justify it as I don't have a weekend type bag at the moment and it would do for that too.
